Measurement of transit system track geometry parameters, under normal operating conditions, is essential for planning and conducting an effective maintenance program. The pertinent parameters are profile, gage, alignment, and cross level. Present methods of determining track conditions are inefficient and highly subjective. Several track geometry measurement methods have been investigated.
